You can put this solution on YOUR website!
One revolution consumes one circumference of distance.\r
\n" ); document.write( "\n" ); document.write( "\"2pi%2865%2F2%29=65pi\" as cm.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Put that in kilometers.
\n" ); document.write( "\"65pi%28cm%29%281%2F100%29%28m%2Fcm%29%281%2F1000%29%28km%2Fm%29\"
\n" ); document.write( "\"%2865pi%29%2F%28100000%29\", KILOMETERS, the circumference of the wheel.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Five Revolutions makes \"5%2865pi%29%2F100000\" kilometers.
\n" ); document.write( "\"325pi%2F100000\"km\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Speed of travel is 25 km/h; how much time?
